Data Structures:

• A data structure is a particular way of organizing data in a computer so that it can be used effectively.

Data Structures Categories:

Primitive or Non-primitive:

1- Primitive Data Structures (Integer, float, char, pointer).

2- Non-primitive Data Structures (Array, List [Non-Linear: Tree, Graph & Linear: Stack, Queue], File).

Physical or Dynamic:

1- Physical Data Structures (Arrays, Matrices, Linked Lists).

2- Dynamic Data Structures ([Linear: Stack, Queue], [Non-linear: Tree, Graph],[Tabular: Hash Table]).

Memory Management Notes:

• Nice topic: https://medium.com/@shoheiyokoyama/understanding-memory-layout-4ef452c2e709
• In stack, the value types always declared inside a stack frame (Activation record) for the function itself.
• Nice to read: https://stackoverflow.com/questions/2565331/fields-of-class-are-they-stored-in-the-stack-or-heap
• Memory parts: Text (instruction), data (global vars), BSS (int i;), heap, stack.
